LeBron James believes the sky is the limit for "super special" rookie Ja Morant, who helped the Memphis Grizzlies defeat the Los Angeles Lakers on Saturday. Morant, the heavy favourite for the Rookie of the Year award, tallied 27 points as the Grizzlies beat James and the Lakers 105-88. He and James swapped jerseys after the game, with the four-time MVP heaping praise on the 20-year-old point guard.
